So Asciidoc is mostly a fresh start + some more default features. Ok. 

You guys seem to be clearly going for this. 
So I'll stop arguing against and start arguing for making everything Asciidoc instead. 
You cannot have Articles, Descriptions, etc be MD now. You either have a Standard or you don't. 

Next, how do I write Asciidoc in Obsidian? Or anywhere else offline on desktop + mobile? 

 Asciidoc actually handles some basic markdown, like headers, code, and bullets.

Use Asciidoctor. 

 Only just got used to MD and Obsidian, damn.
Adapt or die  😂  

 Well if it’s any consolation, I literally did just that not 5 minutes before I read the note about asciidoc. 😆
Now I’m back in OpenBSD where Obsidian is unavailable, trying to set up a new system with asciidoc.
🤷 

 Hahah 🫂  

 Same. 😂 Installed Obsidian a couple months ago.
